SEISMIC MIGRATION BY GAUSSIAN BEAMS SUMMATION

Abstract

Searching for composite traps of hydrocarbons is an actual problem of oil- and gas-geology. The development of fast and at the same time accurate methods for migration of surface-recorded seismic data for construction of an image of the geological boundaries in the subsurface remains one of the major directions of development in modern exploration geophysics. The evolution of computers has enabled practical application of various expensive migration algorithms. For example, in seismic prospecting, pre-stack Kirchhoff migration is nowadays widely used.
